Tartan ... I was in a Staples today and saw them. Some of the smaller stores re-merchandised this summer, and had a lot of items withdrawn from their locations. Yet the larger stores have the items, or you can order online. You had me curious, and I checked online, and yes ...

Last week I was trying to get the temporary adhesive glue sticks or tape. The store I was in didn't have them, and told me why! Luckily for me, I have options as to stores, so I know which locations will NOT be getting my business from here-on, just because of the aggravation factor!

Sorry, but I forget which part of the province you are in. If by chance you have a FedEx Kinkos, they also sell FriXions.
Good Luck ... and hopefully you can get them. Much lower costs than at an LQS, especially if you buy the six pack.
